Fan Control on Mojave

Hi,
I completed my build in macOS Mojave,but I can't figure why my CPU fans can't go to desired BIOS settings.
In my BIOS I set my fans at 70 C- 100% but after boot macOS takes control of the fans.
I can see that at 70 C my fans are 2200 rpm with HWMonitor, but can't go to 3000 rpm.
My fans are EK Vardar FF5 3000rpm.
